I remember a video I saw once of a white and black man carrying a gun. First, they showed a white guy walking down the street with an automatic rifle. A cop pulled up and politely asked him what he was doing and he informed him that he was simply asserting his second amendment right and the cop had no basis to hassle him. The cop talked to him for a minute or two and then left. After that, they showed a black guy walking down the street with the same rifle and a cop pulled up, pointed his gun at him and told him to get to the ground while radioing for backup and soon there were five cop cars worth of police surrounding him and putting him in cuffs. His constant statements that he was simply exerting his second amendment rights were ignored.
